Zhāng Nán 章楠 (fl. 1820–1850, 清), zì Hǔshān 虎山, hào Mèngshǐ 夢史, was a mid-Qīng physician of Shàoxīng 紹興 (Zhèjiāng), active in the early Dàoguāng era. Two principal works:
- Yī mén bàng kè 醫門棒喝, 4 juan, 1825 — a polemical critique of contemporary medical practice, especially the over-prescription of Shānghán-school formulae outside their proper indications.
- Língsù jié zhù lèi biān 靈素節注類編, 9 juan, 1834 (KR3ea040) — a topically-organized abridged commentary on the Sùwèn and Língshū with a strongly Neo-Confucian metaphysical framing.
His clinical orientation is broadly wēnbìng-school, with reservations about over-reliance on cooling drugs. He has no transmitted biographical record beyond these works’ prefaces and colophons.
